Hayward SPX3400Z1ECM Variable Speed Pump Motor - 2.7 HP Square Flange

What This Part Is Used For
The Hayward SPX3400Z1ECM is a variable speed pump motor listed as 2.7 HP with a square flange. It replaces the motor portion of a compatible Hayward variable speed pump so the pump can run at multiple speeds for filtration, heating, and cleaner cycles. This component mounts to the pump wet end on the equipment pad.

Why This Part Matters
When a variable speed motor fails, the pump can stop circulating entirely or run erratically, which impacts filtration, heating performance, and chlorination flow. Motor issues can also trigger drive faults and repeated shutoffs that leave pools going cloudy fast. Replacing the correct motor restores reliable circulation and the ability to run the right speeds for the system. This is a common repair when the wet end is still good but the motor has failed from age, water exposure, or electrical stress.
